Crossifre x8 vs x16 - Performance Difference?

I've done fairly extensive searching, but I can't seem to find any recent, in depth analysis of whether a normal user will notice any real performance boost running a crossfire setup in x16 link vs x8.

I ask because I'm building a new system, and although I'm not planning on going xfire initially, I likely will when the 4850 cards go dirt cheap in the far future, and I'm trying to decide if I need to get:

or if I should save some $$$ and just go with

Any info would be greatly appreciated.

    that's a good question i would try for a better board if you can afford it
    there is a good combo deal on that asus board and a asus 4850
  2. Appreciate the reply, but that link is about the results with single cards on various pcie pipeline speeds, not crossfire results.
  3. his link should give you a rough idea on how it would work

    there would be a decrease in fps overall, but not enough for you to actually regret it
  4. Here is a review that should answer all your questions.
    It has 8 x 8, 16 x 4, 16 x 16. Also PCI 1 vs 2.
  5. I went for the Asus board, the gigabyte one was out of stock, and the offer for the $30 off for the mobo/4850 combo was too good to pass up.
